when is bluetooth discoverable

I have had issues with bluetooth discoverability. It seems that the iphone is only discoverable in the bluetooth menu. A real pain when trying to autopair with the car stereo - I don't want to have to go into the BT menu everytime.

I also checked the discoverability with my nokia - no problems when the iphone was in the BT menu but no luck when it was on any other menu.

The stereo pairs fine to start with in the bluetooth screen on the phone. The handsfree is listed as a device, including when disconnected. I can autoconnect to the handsfree when the phone is in the bluetooth menu but that means I need to go settings>general>bluetooth. Surely if I have the bluetooth on it should be discoverable in whatever screen I am in?

Hmm just checked and if I go through the stereo and select the iphone and direct connect it connects happily in whatever screen the iphone is in.

Summary:
The iPhone has been paired successfully and stored in the stereo's memory and a phone.

Autoconnect has been selected in the stereo

It will autoconnect if I have the phone on the bluetooth menu

It will not autoconnect on any other menu screen of the phone

It will connect if I select the phone directly through the stereo in any menu screen of the phone

Therefore it seems that the stereo cannot see the phone through autoconnect.

I do not have any problems with my BT speaker phone. As soon as I turn on the speaker phone it connects to the iPhone. My guess is that it is just some setting that you are missing. Also my GF has BT built into her car and does not have the same issue you are having.

It is a 3g with version3.1.2

any advice???

I am having the same problem with a GTX Bluetooth Visor Speaker Phone Handsfree Kit. I have it paired fine but I have to manually go into the Iphone BT settings and tap on the paired item. It is a pain each time to do this. I found something online that works temporarily. Here is the post:

Ok, the trick is this: (you'll need a landline phone or another cellphone to get it to work) get your phone to pair your device, make sure your iPhone it's registered to the deck, then leave your iPhone on the bluetooth screen where it says "discoverable"... then you'll need to call your cell phone or send a text message to it... THIS TAKES IT OFF OF THE BLUETOOTH SCREEN BUT LEAVES YOUR PHONE IN THE DISCOVERABLE STATE!!!

this works for me, but only for a short time. Any ideas or other suggestions would be welcome. BTW I also have a 3G with 3.1.2 software and jailbroken.
